Abstract: Polyvinyl alcohol (PVOH) was mixed with an nanofibrillated cellulose (NFC) fiber suspension in water followed by casting. The transmission electron scanning (TEM) images revealed that the NFC fibers dispersed well in PVOH. It was found that the presence of NFC could significantly increase the tensile modulus of the nanocomposites nearly threefold. The differential scanning calorimetry (DSC) analysis showed that the NFC could serve as a nucleating agent, promoting the early onset of crystallization. However, at a higher NFC content, it also led to greater thermal degradation of the PVOH matrix. The nanocomposites were found to be sensitive to moisture content and dynamic mechanical analysis (DMA) tests showed that at room temperature, the storage modulus increased with decreasing moisture content. The solubility of carbon dioxide (CO2) in the nanocomposites depended on their moisture content and decreased with the addition of NFC. Moreover, the desorption diffusivity became higher as the amount of NFC increased.
